What is the difference between hot-dip galvanized steel pipe and hot-dip galvanized steel pipe SC

1. Different representations: hot-dip galvanized steel pipes generally refer to the standard nominal diameter of water pipes, which are expressed in DN. Hot-dip galvanized steel pipe SC means that the wire is laid through steel pipe (low-pressure fluid welded steel pipe). SC is an ordinary welded steel pipe, which is equal to water professional DN. SC has welded steel pipe concealed. Generally, the pipe wall is relatively thick. laying method.

2. The process is different: the hot-dip galvanized coating is thick, so the anti-corrosion ability is strong. The hot-dip galvanized steel pipe has uniform SC and good surface quality, and the thickness of the coating is generally between a few microns and more than ten microns. Hot-dip galvanizing is a chemical treatment and belongs to an electrochemical reaction. The hot-dip galvanized steel pipe SC is a physical treatment, just brushing a layer of zinc on the surface, and there is no galvanized inside, so the hot-dip galvanized steel pipe SC is easy to fall off. Hot-dip galvanizing is often used in building construction.

The common point between hot-dip galvanized steel pipe and hot-dip galvanized steel pipe SC is that both belong to galvanized steel pipe.
